I think the kernel.org post proves the parent point rather than contradicts it.

14 CPU cores total for running a website like kernel.org is laughable. This is not worth burning cycles in Anubis on client's devices, this is not worth the time of the engineer who worked on it. Provisioning more hardware would have been literally better for everyone.
